Abstract
The invention relates to a method for oxidizing primary alcohols in order to obtain aldehydes and/or carboxylic acids. The reaction takes place in the presence of a catalyst supported on aluminium oxides or aluminium silicates and containing palladium, platinum, cobalt, rhodium, ruthenium, iridium, rhenium, optionally with co-catalysts.
Claims9
A method of oxidation of primary alcohols, characterized in that primary alcohols containing 4 to 32 carbon atoms in a liquid state are brought in contact with a catalyst containing
- (a) palladium, platinum, cobalt, rhodium, ruthenium, iridium, rhenium and/or osmium and a co-catalyst containing
- (b) bismuth, antimony, arsenic and/or phosphorus and
- (c) aluminum oxides and/or aluminum silicates as the support in the absence of solvents and in the presence of molecular oxygen (O2) at a reaction temperature of 20 to 120° C.
